G3 Alarm app for iPhone and iPad

Chuango G3 GSM/SMS Alarm System
Chuango G3 is an elegantly powerful alarm system that is easy to install and use. All it needs is a regular working 2G SIM card, and it can be armed/disarmed via a phone call or SMS text message from preauthorized phone numbers; preauthorized remote controls; or smartphone app commands. Upon detection of intrusion, the G3 will sound the built-in siren and call and/or text out to you for appropriate action.
The intuitively designed Chuango G3 app interface enables you to effortlessly adjust system settings on the go: arm/disarm, home mode, remote voice memo or listening in
